sudo apt update; sudo apt upgrade前几天尝试运行，出现了一个关于 dpkg 的错误，这是我以前从未见过的，而且谷歌似乎也没有提供太多帮助。
我仅粘贴输出，因为我不知道发生了什么：
sudo apt upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
steam:i386 : Depends: steam-devices:i386
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

The following packages were automatically installed and are no longer required:

The following NEW packages will be installed:

有没有比我更熟悉 apt 和包管理的人能解释一下这些错误的含义以及我该如何诊断/修复问题。我真的不知道从哪里开始。
系统是 debian 9（我认为）
答案1
最近我遇到了同样的问题，在我的 Debian 9 上收到 Steam 发出的缺少依赖项通知后，我寻找解决方法。我已在其上安装了 Synaptic 包管理器（您可能也默认安装了它），因此我设法从那里删除了损坏的包：
- 界面左侧的软件包按状态分类：已安装、未安装、损坏……）。您需要检查损坏的软件包并点击“应用”按钮。
- 然后我从 Synaptic 升级了 Debian（“标记所有升级”，然后“应用”）
- 然后
steam-devices:i386像往常一样从终端安装。 - 我遵循了 apt 的所有建议（安装了适用于我的图形驱动程序的所有推荐软件包等）并让我的 Steam 正常运行。
如果您是 Synaptic 的新用户，您需要知道您需要以 root 身份才能使用它（它会询问），并且当 Synaptic 打开时，您将无法从命令行使用 apt。
